Thanks everyone. The discussion was useful for me.
BTW, I'm not doing anything strange. Just the equivalent of  starting with:

    7   0  25  10
    0   9   7  12
    3   2   1   0

and sorting the columns:

    0   0   1   0
    3   2   7  10
    7   9  25  12

Which allows me to get max and median values for each column. (Rick, 
each row is a different trace file and each column is a scan.)
